" You know, he (Nietzsche) belongs to the people living east of the Rhine where there is no anima psychology yet; masculine psychology, the Puer Eternus psychology, prevails there on account of the youth of those tribes. In the older civilization west of the Rhine the anima problem comes up, but east of the Rhine there is generally the problem of the relationship between man and the subordinate principle — an idea or an enthusiasm, for instance, or a big enterprise. It is entirely the psychology of the youth who is entering life where the world consists mainly of men. There are female appendages who serve a certain purpose, for the propagation of the tribe or for the romantic feelings, but there is no other use for them. Therefore, you actually see the idea spreading again that a woman belongs in the kitchen and is only useful to produce children — that she has no psychological problem, andno potentiality for soul-development. "
